1g = 9.80 ^m/s²
All projectiles accelerate down at 9.80 ^m/s²
"Rest" means v_o = 0

When solving every problem include

• a simple drawing showing the initial and final state being described,
• a list of givens with units next to each number,
• the equation being used with only variables,
• rearranged equation with only letters to isolate the unknown variable,
• equation with plugged in number and units at least once,
• any math steps -as needed,

The answer with numbers AND correct units. (The units should match the units given in the problem. i.e. mph in the problem means the answer should be in miles, hours or mph. Centimeters in the problems means the answer should be in cm, cm/s or ^m/s².

1. How much distance is covered by a runner who starts from rest in the race and accelerate at 5.00 ^m/s² in 2.00 seconds?
2. While Calvin is doing a physics experiment outside with a radar gun, he notices that after 3 seconds a car reaches a speed of 20.0 m/s while accelerating at 3 ^m/s². What was the initial velocity of the car?
3. A squirrel drops 1.50 m from a tree branch to the ground. How much time did it take for him to reach the ground?
4. A billiard ball is rolling at 0.50 ^m/s then it slows to 0.15 ^m/s in 2.00 m. What is the ball’s acceleration?
5. Calvin hears a loud roar that causes him to turn around and notice a rocket traveling at 25 ^m/s. The rocket undergoes an acceleration of 3 g’s. How fast is the rocket traveling after 100 m?
6. A dragster starts from rest and undergoes an acceleration of 4 g’s before reaching its top speed of 100 ^m/s. How much time did it take to reach this top speed?
7. While trying to leave school in hurry, a senior, Deathwish Dan, starts from rest and floor’s his Smart Car™ to reach a speed of 10 ^m/s² in 100m. What was his car’s acceleration in ^m/s² and g’s?
8. A baseball player throws a ball straight up until it reaches an apogee of 5.0 m above it release point. How fast was the ball traveling when it left hi hand. (“Apogee” means the highest point of flight. As such a projectile’s velocity is zero.)
9. While traveling down the road you notice a state trooper’s car accelerate from 25 ^m/s to 35 ^m/s on 1.5 seconds. What was the acceleration of the car in ^m/s²?
10. At the Indy 500 race the car at the front of the pack at the start of the race is traveling at 36 ^m/s² when it accelerates at 15.0 ^m/s² for 4 seconds? What is the final velocity of the race car?
